Cold rolled steel pipe is manufactured through a cold rolling process at room temperature (below the metal recrystallization temperature). It is typically produced from hot - rolled seamless steel pipe billets.
In terms of characteristics, it boasts precise dimensions with tight tolerances for outer diameter, inner diameter, and wall thickness. The surface finish is excellent, with high smoothness and no oxide scale defects. Moreover, the cold working process induces work hardening, resulting in high strength and hardness. It can also produce extremely thin - walled pipes that are difficult to achieve by hot rolling.
